Evaluation of wheelchair resistive forces during straight and turning trajectories across different wheelchair configurations using free-wheeling coast-down test.
The purpose of this study was to develop a simple approach to evaluate resistive frictional forces acting on manual wheelchairs (MWCs) during straight and turning maneuvers. Using a dummy-occupied MWC, decelerations were measured via axle-mounted encoders during a coast-down protocol that included straight trajectories and fixed-wheel turns. Eight coast-down trials were conducted to test repeat...
متن کاملComparison of Upper Limb Joint Forces during Straight Line and Turning Wheelchair Maneuvers
The objective of this study was to explore the joint kinetics of upper extremities during wheelchair maneuvers. A high incidence of musculoskeletal injuries has been reported due to the overuse and high repetitive motion of wrist, elbow and shoulder during wheelchair propulsion. Studies have been conducted with the use of a dynamometer or treadmill to simulate propulsion on level or inclined su...
متن کاملChanges in inertia and effect on turning effort across different wheelchair configurations.
When executing turning maneuvers, manual wheelchair users must overcome the rotational inertia of the wheelchair system. Differences in wheelchair rotational inertia can result in increases in torque required to maneuver, resulting in greater propulsion effort and stress on the shoulder joints. The inertias of various configurations of an ultralightweight wheelchair were measured using a rotati...
متن کاملCoupling of breathing and movement during manual wheelchair propulsion.
The hypothesis of this study was that stable coordination patterns may be found both within and between physiological subsystems. Many studies have been conducted on both monofrequency and multifrequency coordination, with a focus on both the frequency and phase relations among the limbs. In the present study, locomotor-respiratory coupling was observed in the maintenance of small-integer frequ...
متن کاملPropulsive Work Cost and Shoulder Movement during Lightweight and Ultra Lightweight Manual Wheelchair Propulsion in Pediatrics
Lightweight (K4) and ultra-lightweight (K5) wheelchairs are commonly used as mobility devices by pediatric manual wheelchair users. In this study, instrumented pushrims and wireless motion tracking were used to measure energy cost and shoulder flexion during manual wheelchair propulsion. Eight pediatric (age=1218 yrs) manual wheelchair users propelled a K4 and K5 wheelchair across a level tiled...
